A reciprocating compressor is a core part of air conditioning and heat pump systems, compressing refrigerant into high-pressure gas. It's essential for effective cooling.

Reciprocating Compressor

A reciprocating compressor, also known as a piston compressor, is a vital component of an air conditioning unit or heat pump. Positioned in the outdoor unit, it compresses refrigerant into a heated gas before moving it through the cooling cycle.

In a reciprocating compressor, air is drawn into the cylinder on the intake stroke and then compressed on the piston’s upstroke. The pressurized gas is then delivered through an outlet valve to perform cooling work. This type of compressor can provide higher pressure ratios than rotary compressors, making it more efficient at lower speeds.

Features of Reciprocating Compressors

Reciprocating compressors are often designed with reinforced steel shells to withstand high operating pressures and to keep contaminants out. These compressors are typically quieter and more durable than other types due to their construction, which includes sealed oil and refrigerant to optimize longevity and reliability.

HVAC Maintenance for Your Compressor

To keep the compressor operating at its best, annual maintenance for your air conditioner or heat pump is essential. During a maintenance visit, the HVAC technician will inspect, clean, and make necessary adjustments to the outdoor unit to ensure efficient cooling.

AC Compressor Repair or Replacement

If you notice your AC or heat pump isn’t cooling effectively, unusual noises from the outdoor unit, or pooling around the compressor area, these signs may indicate a problem with the compressor or another component. In such cases, it’s best to consult a professional HVAC technician for repair or replacement as needed.
